Page orientation is important when printing on pre-printed paper such as letterhead and pre-punched paper.

NOTE: Set LetterH Dup Mode (Letterhead Duplex Mode) to Enable and Paper Type to Letterhead, Preprinted, or Prepunched from the operator panel or the printer driver, even if printing single sided (simplex) jobs.

To load a Letterheaded Paper in the Main or Optional Tray:Load Face Up with the letterhead entering last

To load a Letterheaded Paper in the Main or Optional Tray for a Duplex (2-sided) Print:

To load a Letterheaded Paper in the SSF (Single Sheet Feeder):Load Face Down with Letterhead Entering First

Use only high-quality envelopes that are designed for use in laser printers

Set the print media source to the single sheet feeder or the standard 250-sheet tray

Set the paper type to Envelope, and select the correct size of envelope from the printer driver

Use envelopes made from 75 g/m2 (20 lb bond) paper. You can use up to 105 g/m2 (28 lb bond) weight for the envelope feeder as long as the cotton content is 25 % or less. Envelopes with 100 % cotton content must not exceed 90 g/m2 (24 lb bond) weight

Use only freshly unpackaged, undamaged envelopes

Use envelopes that can withstand temperatures of 205 °C (401 °F) without sealing, excessive curling, wrinkling, or releasing hazardous emissions

Adjust the guide to fit the width of the envelopes

To load an envelope into the single sheet feeder, insert the envelope with the flaps closed and the short-edge of the envelope facing into the printer. The print side must be facing down

Use one envelope size during a print job

Ensure that the humidity is low because high humidity (more than 60 %) and the high printing temperatures may seal the envelopes

For best performance, do not use envelopes that:

Have excessive curl or twist

Are stuck together or damaged in any way

Contain windows, holes, perforations, cutouts, or embossing

Use metal clasps, string ties, or metal folding bars

Have an interlocking design

Have postage stamps attached

Have any exposed adhesive when the flap is in the sealed or closed position

Have nicked edges or bent corners

Have rough, cockle, or laid finishes

To load an envelope into the single sheet feeder, insert the envelope short edge feed with the flap closed and the print side down. Ensure that the flap comes at the right when you face towards the printer.
